Using gumdrops and toothpicks, students conduct a large-group, interactive ozone depletion model. Students explore the dynamic and competing upper atmospheric roles of the protective ozone layer, the sun's UV radiation and harmful human-made CFCs (chlorofluorocarbons).
Have you ever noticed that different species of birds have very different …
Have you ever noticed that different species of birds have very different types of beaks? In this activity, learn about adaptation and how a bird\'s beak shape helps them to find food and survive in their environment.
This pathway explores how physical features of a species can change over …
This pathway explores how physical features of a species can change over time in response to environmental factors influencing survival. Learn about well known case studies like Darwin's finches and peppered moths, and conduct your own investigations through simulations.

In this activity, students learn about their heart rate and different ways it can be measured. Students construct a simple measurement device using clay and a toothpick, and then use this device to measure their heart rate under different circumstances (i.e., sitting, standing and jumping). Students make predictions and record data on a worksheet.
Lighting is responsible for nearly one-third of the electricity use in buildings. …
Lighting is responsible for nearly one-third of the electricity use in buildings. One of the best ways to conserve energy is to make sure the lights are turned off when no one is in a room. This process can be automated using motion sensors. In this activity, students explore material properties as they relate to motion detection, and use that knowledge to make design judgments about what types of motion detectors to use in specific applications.
